How to use the Grade Calculator
Enter each assignment with its score and weight
Fill in the score, maximum score, and weight (%) for each assignment. Click 'Add assignment' to add more rows. The contribution to your final grade updates live next to each row.
Check the total weight
The weight total indicator shows the sum of all entered weights. For an accurate final grade, weights should add up to 100%. A warning appears if they don't.
Set a target grade
Enter your target final grade percentage in the 'Target final grade' field. The calculator instantly shows what score you need on the remaining assessments to hit that target.
Switch between US and UK grading
Use the toggle to switch between US letter grades (A/B/C/D/F) and UK undergraduate honours classifications (First, 2:1, 2:2, Third, Fail). Your current average updates instantly.
About this Grade Calculator
Keeping track of your grades throughout a semester is far better than waiting for a surprise at the end of term. Our free grade calculator lets you enter all your assignments with their individual weights to see your running weighted average at any point in the year. You can also set a target grade and instantly see exactly what score you need on remaining assessments. Weighted grading means not all assignments count equally. A short quiz worth 5% matters far less than a final exam worth 40%, even if you score identically on both. Our weighted grade calculator handles this correctly — enter each assignment's weight and we do the maths automatically. Grading standards vary by country. In the US, 90–100% is an A, 80–89% a B, 70–79% a C, and so on. The UK undergraduate system uses different thresholds: First Class starts at 70%, Upper Second (2:1) at 60%, Lower Second (2:2) at 50%, and Third Class at 40%. These lower thresholds reflect the UK's more conservative marking culture. Our final grade calculator supports both systems and shows your letter grade or classification alongside the percentage so you always know where you stand.
Frequently Asked Questions
Multiply each assignment score by its weight, sum those products, then divide by the total weight. For example: (85 × 0.4) + (90 × 0.6) = 34 + 54 = 88% overall.
Use the formula: Required = (Target − Current × (1 − Exam Weight)) ÷ Exam Weight. Our grade calculator solves this automatically — enter your current grade, target grade, and the final exam weight.
Standard GPA scale: A = 4.0, A− = 3.7, B+ = 3.3, B = 3.0, B− = 2.7, C+ = 2.3, C = 2.0, D = 1.0, F = 0.0. Some institutions use a +/− system while others use whole numbers only.
In the US, grades are A (90–100%), B (80–89%), C (70–79%), D (60–69%), F (below 60%). The UK undergraduate system uses: First Class (70%+), Upper Second / 2:1 (60–69%), Lower Second / 2:2 (50–59%), Third Class (40–49%), Fail (below 40%). UK marking is more conservative, so the thresholds are lower.
Requirements vary by institution, but US colleges typically require a minimum 2.0 GPA to graduate. Graduating cum laude usually requires 3.5+, magna cum laude 3.7+, and summa cum laude 3.9+. The Dean's List generally requires a 3.5 GPA or higher for a given semester.
